Flight is a free and open-source microframework for the PHP programming language. It is designed to be fast, simple, and extensible, with a focus on building RESTful web applications and APIs. Flight emphasizes minimalism, performance, and compatibility with AI-powered development tools.[1][2]
History
editFlight was originally created by Mike Cao and first committed to GitHub on March 31, 2011.[3] The framework was hosted under the repository mikecao/flight until 2024, when Cao transferred ownership to a new organization, flightphp, to ensure continued development.[4] n0nag0n became the primary maintainer following the transfer.[5] Early versions of Flight addressed security vulnerabilities, such as a denial-of-service attack issue in versions prior to 1.2, reported in CVE-2014-125127.[6] The framework transitioned from version 2 to 3 with backward compatibility in mind, avoiding major breaking changes to maintain API stability over a decade.[7] As of January 2026, the latest release is version 3.17.4, released on December 27, 2025.[8]
Development philosophies
editFlight adheres to a minimalist philosophy, providing a lightweight core without dependencies to reduce overhead and improve performance.[9] It is positioned as a "micro-framework," offering essential tools like routing and response handling while allowing developers to extend functionality as needed.[10] The framework prioritizes simplicity for beginners, stable APIs for long-term projects, and flexibility for scaling from prototypes to enterprise applications.[11] In recent years, Flight has been optimized for AI-friendly development, with clean architecture that integrates well with coding assistants and large language models.[12] Benchmarks from TechEmpower highlight its speed, outperforming frameworks like Laravel, Symfony, and Slim in plaintext and JSON requests.[13]
Features
editFlight's core features include:
Routing: Simple definition of routes using methods like Flight::route().[14]
Response handling: Built-in support for JSON responses via Flight::json() and HTTP caching.
Extensibility: No built-in dependencies, allowing integration with other libraries or ORMs.
Performance: High throughput, with reported rates of over 190,000 requests per second in benchmarks.[15]
Compatibility: Supports PHP 7.4 and later, including PHP 8+.
The framework is installed via Composer and includes a skeleton application for quick setup.[16]
Major packages
editflightphp/core: The primary framework package.[17]
flightphp/skeleton: A boilerplate application with pre-configured structure and examples.[18]
flightphp/active-record: Micro Active Record library in PHP, supports chain calls, events, and relations.[19]
flightphp/session: A lightweight, file-based session handler for the Flight framework. It supports non-blocking behavior, optional encryption, and auto-commit functionality.[20]
flightphp/apm: Application Performance Monitoring for Flight PHP.[21]
flightphp/runway: Console app for the Flight PHP Framework.[22]
Flight can be integrated with other PHP packages for additional functionality, such as databases or templating engines.
